Vrana made it 2-1 at 8:55, scoring on a breakaway. Vrana, who was serving a bench minor, came out of the box to receive a pass from Gustav Lindstrom.
"I was worried we might go to 4-on-4 and not have him, but I wanted him to be out there with [Dylan] Larkin and [Filip] Zadina after the kill," Blashill said of his decision to use Vrana to serve the penalty. "It worked out really well."
Stecher made it 3-1 with his second of the game at 11:15, pinching in to take a pass from Danny DeKeyser and tuck it behind Lankinen.
"That was just a great pass from [DeKeyser]," Stecher said. "The goalie thought he was going to shoot and he put the puck right on my tape. I just had to put it in the empty net."
Stecher, who made his NHL debut on Oct. 25, 2016 for the Vancouver Canucks, had never scored twice in the same month.
"I was trying not to think about a hat trick, but everyone in the locker room was telling me to shoot every time I got a chance," Stecher said. "It would have been nice, but I'm very happy to get my first two-goal game."
Michael Rasmussen scored into an empty net at 18:34 of the third period.
"Detroit's a good team and they are playing a patient, simple game," Keith said. "We only got one goal tonight, but we had chances. We've just got to find a way to get those extra goals on Saturday."
NOTES: Vrana became the second Red Wings player to score in his debut with the team this season. Bobby Ryan did it Jan. 16 against the Hurricanes. … Lankinen was 4-0-0 with a .962 save percentage against Detroit this season. … Stecher was the first Red Wings defenseman with a two-goal game since Nick Jensen on Oct. 11, 2018 in a 5-3 loss to the Toronto Maple Leafs.
